Resources of lignocellulose from Agriculture and forestry waste like straw in our country is abundant.Thus,It is far significant to use lignocellulose as raw materials to produce alcohol,which can help solve the problems of oil shortage and environmental pollution and to promote the sustainable development in economy and society .In this paper,we researched systematically in some respects,such as pretreatment to the wheat straw,degradation kinetics of the main components,simultaneous saccharification and fermentation of crude fibre and the preparation and characterization of xylo-oligosaccharide and Lignin base activated carbon by using hemicellulose.Considering that
wheat straw is featured by its dense and difficult hydrolytic structure,in this paper we retreated wheat straw by using propionic acid respectively.

In our country, such as straw agriculture and forestry waste lignocellulose resources are abundant, in this as raw materials instead of food production fuel ethanol, for our country to solve the problems of petroleum deficiency and environment pollution, and promote sustainable economic and social development, have important significance. This topic on wheat straw pretreatment, the main component of the degradation dynamics, crude fiber synchronous saccharification fermentation, hemicellulose preparation xyol-oligosaccharides and lignin base activated carbon preparation and characterization on the key techniques such as the system research. For wheat straw structure compact, difficult to directly by enzyme hydrolysis characteristics, this paper respectively by means of propionic acid method on wheat straw pretreatment.

Of straw and other agricultural and forestry residues the lignocellulose resource-rich, and so instead of grain as raw material to produce fuel ethanol, solve the oil shortage and environmental pollution problems, as well as to promote sustainable economic and social development, are of great significance. The subject of the pretreatment of wheat straw, the main component of the degradation kinetics, simultaneous saccharification and fermentation of crude fiber, Preparation of hemicellulose of XOS as well as lignin-based activated carbon preparation and characterization of the key technologies of the system. Dense structure of wheat straw, and difficult to direct enzyme hydrolysis characteristics, this paper were used the propionic method of pretreatment of wheat straw.
